Definitions

• the present invention relates to the field of perfumery. It concerns, more particularly, a method to confer, improve, enhance or modify the odor properties of a perfuming composition or a perfumed article, which method comprises adding to said composition or article a fragrance effective amount of 3-methyl-cyclopentadec-5-en-1-one.
• the invention also concerns a perfuming composition or a perfumed article containing 3-methyl-cyclopentadec-5-en-1-one as active perfuming ingredient.
• Another object of the invention is a composition containing 3-methyl-cyclopentadec-5-en-1-one and 3-methyl-cyclopentadec-4-en-1-one, and wherein the weight proportion of 3-methyl-cyclopentadec-5-en-1-one is equal to 70% or more.
• the invention further provides a method of use of this latter composition in perfumery.
• 3-Methyl-cyclopentadec-5-en-1-one is a macrocyclic ketone and an unsaturated homolog of muscone, a compound which is well appreciated in perfumery. Owing to the presence of a ring double bond, there are several possible position and configuration isomers for this molecule. The structure of some of them is known. Thus, the structure of the above-mentioned enone, as well as that of several of its isomers, has been described in the literature, mostly in connection with organic syntheses, namely that of muscone. However, there has been no mention of any possible useful odor properties for these compounds.
• ketones (I), or mixtures of ketones (I), are cited in said patent, namely 3-methyl-cis-cyclopentadec-4-en-1-one (example 4) and 3-methyl-trans-cyclopentadec-4-en-1-one (example 17), as well as a mixture containing essentially the trans isomers of 3-methyl-cyclopentadec-4 and 5-en-1-one (examples 1 et 2), we were unable to find any description of the individual properties of any of these ketones or mixtures, or of the possible olfactive differences between them.
• patent describes either mixtures of isomers, containing both 3-methyl-cyclopentadec-5-en-1-one and 3-methyl-cyclopentadec-4-en-1-one, or the cis isomer of the latter, while patent GB 2 058 786 only describes the preparation of 3-methyl-cyclopentadec-4-en-1-one without specifying any isomeric proportions.
• 3-methyl-cydopentadec-5-en-1-one, and its cis and trans isomers are equally convenient for fine perfumery and technical perfumery applications.
• Their tenacity on textiles renders them particularly useful for perfuming laundry detergents and fabric softeners. In these applications, they can be used on their own or in admixture with other perfuming ingredients, solvents or adjuvants of current use in the art.
• proportions in which these compounds can be used depend on the fragrance effect that one desires to achieve, as well as on the nature of the other perfuming co-ingredients in a given composition.
• concentrations of the order of 5 to 10%, or even 20% or more by weight, relative to the weight of the perfuming composition or perfume into which they are incorporated.
• a base perfuming composition was prepared by admixing the following ingredients:
